PECIFICATION forming part of Letters Patent No. 344,625, dated .Tune 29, 1886.

Application filed January 17, 1885.

To all whom it may concern:

Be it known that I, ADOLPII CLAUS, of Low ell, county of Middlesex, State of Massachusetts,have invented an Improvement in Loom- Shuttles, of which the following description, in connection With the accompanying drawings,is a specification,likeletters ou the drawings representing like parts.

This invention relates to that class of shuttles that have spindles which are adapted to engage a bobbin having an inside groove.

rlhe spindles of the class of shuttles referred to, so far as I am aware, have prior to my invention been made from caststeel, as the spring having one of the bobbin-engaging projections of a spindle is subjected to considerable strain.

In accordance with my invention the main part of the spindle, which may be of cast metal, has a loosely-conneeted auxiliary spindle-section which is readily detachable from the main part of the spindle, and to operate the said spindle-section and cause it to engage the usual inside groove when the spindle iS turned down into the shuttle it is provided With a curved tail-piece which Strikes a stud located just below the usual pivotpin of the shuttle'spindle.

rlhe invention consists in the shuttle-spindle constructed and operating substantially as hereinafter particularly set forth and claimed.

Figure l represents a loom-shuttle embodying my invention, part of the body of the shuttle being broken ont, the spindle and bobbin and Itheir co-operating parts being in section, the bobbin being shown locked on the spindle and within the body of said shuttle; and Fig. 2 is a similar view with the spindle turned out from the shuttle-body and the bobbin removed, the spindle being in elevation.

Theshuttle-body A, ofany preferred or usual construction, is provided with a pivot-pin, a, passing transversely through it, and with a iiat spring, a', secured thereto by a screw, a2, the free end Iof the said spring acting upon one edge of the head 2 of the spindle or against the corner?) thereof, according to the position of the spindle, as shown in the drawings, the said spring acting in usual manner on the spindlehead to retain the spindle either Within the sl1uttle-body,asin Fig. 1,0r elevated, as

in Fig. 2. The spindle I), having the usual loekingshouldenf, to engage the inside groove, g, in the interior ofthe bobbin g', has the under side of its head notched, as at c, to permit the head of the spindle to be readily removed or applied without driving out the pivot-pin, as nouT necessary in most shuttles.

I have provided the Spindle b with the auX- iliary spindleseetion h,having a shoulder, h', to engage theinside groove of the bobbin when the spindle is turned from the position Fig. 2 into the position Figl. The end ofthe Spindlen section h most remote from the pivot-pin a is held loosely in place on the spindle, as hereinA shown, by an elastic ring or band, It, which encompasses the spindle and the end of the said spindle-seetion, as shown. The other end of the Spindle-section is provided with a curved tail-piece, h2, which is normally kept in contact with the stud 5 by the band h3.

Vhen the spindle is in the position shown in Fig. 2, the curved tail ofthe spindlesection is brought into such position with relation to the stud 5 as to permit the elastic loop or band h3 to throw the spindle-section in close to the spindle, thus removing its shoulder 71. from the inside groove ofthe bobbin, when the latter may be readily removed.

Upon turning the spindle about its pivot into the body of the shuttle, as in Fig. 1, the tail-piece h2, as its curved surface is moved in contact with the stud 5, causes the spindlesection to be moved outward or away from the main body of the spindle, so that the projec tion or shoulder h enters the inside groove, g, of the bobbin g,whieh has been previously placed on said spindle, thereby retaining the bobbin in place on the spindle, as shown in Fig. l.

The spindle maybe readily removed from the shuttle by removing the spring a', as will be clearly understood.

Heretofore in shuttles employing bobbins formed with inside grooves one of the engaging hooks or projections on the spindle has been made as a spring; but weakening of the said spring for any reason enables the bobbin to escape from the spindle.

1. The shuttle-body, spindle b, spindlesection h, having a tail-piece,and elastic band for connecting the said spindle and its section, combined with the spindle pivot-pin, and a stud co-operating with the spindle-section to engage it with and disengage it from a bobbin placed on the spindle, substantially as described. p Vy 2. The shuttle-body, its pivot-pin, the shouldered Spindle b, and the independent spindle section, combined with an elastic band to yretain the said spindle-section to the spindle7 and with means to move the latter away from' the main body of the spindle, substantially as and for the purpose set forth.

3. The shuttle-body, its pivot-piatte Shout dered spindle b, and the independent spindle- 'section having a shoulder, h', combined with 4 set forth. l

In testimony whereof I havei signed my name j to this specification in the presence of two subscribing witnesses.
